I think you get what you pay for. They work but not the best airflow and the noise is too much. Unfortunately I will send them back and get a nice stamp. I had no idea how good my nearly $2000 system actually was until I added them above. It's not the airflow noise that turns my ghost cooler off, just a cheap rattling noise that goes away when you push it down, but I'd rather spend the extra money for a set without this problem, I haven't skimped on my system and shouldn't have skimped on fans. I was actually wrong in assuming they would be quiet, although other reviewers said they were quiet.
